摘要： A vehicle drive device is provided that can suppress the increase in dimension in the radial direction while ensuring a sufficient speed reduction ratio. Two driving force sources are arranged on a first axis, two output members are arranged on a second axis, two counter gear mechanisms are arranged on a third axis. A planetary gear mechanism is configured to transmit rotation from the two counter gear mechanisms to the output members, and is disposed so as to overlap with both of the two counter gear mechanisms as seen in an axial direction along and axial direction.

摘要： A first case portion includes an end wall portion disposed on a first axial side with respect to a transmission. A second case portion is disposed on the first axial side with respect to a rotor of a rotary electric machine, and includes a first support portion that supports a rotor shaft and a second support portion disposed on a second axial side with respect to the rotor of the rotary electric machine to support the rotor shaft. The second support portion includes a bearing attachment portion to which a rotor bearing for supporting the rotor shaft is attached, and radially extending portion that extends from bearing attachment portion toward an outer side in a radial direction. A speed reducer is disposed between the radially extending portion and the end wall portion in axial direction to face the radially extending portion and the end wall portion in the axial direction.

摘要： A vehicle driving apparatus including: a rotating electrical machine that acts as a source of driving force for a first wheel and a second wheel; a speed reduction device that reduces a speed of rotation of the rotating electrical machine; a differential gear device that distributes, to the first wheel and the second wheel, the driving force transmitted from the rotating electrical machine via the speed reduction device; a case that houses the rotating electrical machine, the speed reduction device, and the differential gear device; and an oil circulator.
